Trauma in pregnancy. Predicting pregnancy outcome.

A multicenter study involving three American College of Surgeons Level 1 trauma centers was undertaken to assess parameters that may predict fetal outcome. The records of 93 injured pregnant patients admitted from April 1, 1985, to March 31, 1990, were reviewed. There were three maternal deaths (3%) (mean Injury Severity Score, 43). Fourteen fetal/neonatal deaths (15%) occurred during the acute care admission period. Of these, eight were fetal deaths (two associated with maternal death), four were cases of elective abortions, and two were neonatal deaths. In general, the maternal physiologic and laboratory parameters assessed failed to accurately predict pregnancy outcome, while Injury Severity Score did differ significantly between patients whose pregnancies were viable (Injury Severity Score = 6.2) and those whose pregnancies were nonviable (Injury Severity Score = 21.6). Unique to this study were the findings that the Glasgow Coma Score also differed significantly in patients with viable (Glasgow Coma Score, 14.5) and nonviable (Glasgow Coma Score, 12.0) pregnancies, while fetal heart rate at admission to the emergency department did not. In this study, the incidence of fetal death was increased following direct uteroplacental fetal injury (100% of cases), maternal shock (67%), pelvic fracture (57%), severe head injury (56%), and hypoxia (33%). The adequacy of noninvasive maternal monitoring in assessing fetal well-being is challenged, and a discussion of diagnostic modalities for assessment for the injured gravida is set forth.

Reversal of lidocaine with epinephrine epidural anesthesia using epidural saline washout.

BACKGROUND AND OBJECTIVES: Prolonged motor and sensory block following epidural anesthesia can be associated with extended postoperative care unit stays and patient dissatisfaction. Previous studies have demonstrated a more rapid motor recovery following the administration of epidural crystalloids in patients who had received plain bupivacaine and lidocaine epidural anesthesia. However, epinephrine is commonly added to local anesthetics to improve the quality and prolong the duration of the epidural block. The objective of this study was to determine the relationship of 0.9% NaCl epidural catheter flush volume (i.e., washout) to the recovery of motor and sensory block in patients undergoing 2% lidocaine with epinephrine epidural anesthesia. METHODS: A prospective, randomized, double-blind study design was utilized. Thirty-three subjects scheduled for elective gynecologic or obstetrical surgical procedures underwent epidural anesthesia using 2% lidocaine with epinephrine (1:200,000). A T4 dermatome level of analgesia, determined by toothpick prick, was maintained intraoperatively. Following surgery, subjects were randomized to 1 of 3 treatment groups. Group 1 (control, n = 11) received no epidural 0.9% NaCl (normal saline [NS]) postoperatively. Group 2 (15 mL NS x 1, n = 10) received an epidural bolus of 15 mL NS. Group 3 (15 mL NS x 2, n = 12) received an epidural bolus of 15 mL NS postoperatively and a second 15-mL NS bolus 15 minutes later. Assessment of motor and sensory block was performed at 15-minute intervals until complete motor and sensory recovery. RESULTS: Times to partial and full motor and sensory recovery were significantly faster in the epidural NS groups than in the control group. Full motor recovery was more rapid in subjects receiving two 15-mL NS epidural NS boluses (30 mL total) compared with those receiving a single 15-mL NS bolus (108 +/- 9 min v 136 +/- 13 min) and significantly faster than control group subjects (153 +/- 14 min). Both NS x 1 and NS x 2 epidural bolus groups experienced significantly reduced times to complete sensory recovery when compared with the control group (NS x 1 = 154 +/- 13 min, NS x 2 = 153 +/- 9 min, control 195 +/- 14 min). CONCLUSIONS: A more rapid recovery of motor and sensory block in patients undergoing 2% lidocaine with epinephrine epidural anesthesia can be achieved with the use of 30 mL NS epidural washout.

Severely injured geriatric patients return to independent living: a study of factors influencing function and independence.

Our previous work demonstrated that geriatric trauma patients (age greater than 65 years) consume disproportionate amounts of health care resources. In the past we hypothesized that late mortality is high, long-term outcome is poor, and return to independence is low in a severely injured geriatric population. Of 6,480 trauma admissions over 5 years, geriatric patients (n = 495) with blunt trauma injury (n = 421) and an ISS greater than 16 (n = 105) who survived until discharge (n = 61) underwent long-term follow-up (mean = 2.82 years). We surveyed 20 measures of functional ability; 10 measures of independence; availability and use of rehabilitation resources; employment history; alcohol use; support systems; and nursing home requirements. Of the 105 patients, 7 were subsequently lost to follow-up. Among the remaining 98, 44 (44.9%) died in hospital and 54 (55.1%) were discharged and interviewed. The mean age of the contacted patients was 72.6; their mean ISS was 23.3. Forty eight of 54 (88.9%) were alive at the time of interview, while 6/54 (11.1%) had died. Although only 8/48 patients regained their preinjury level of function, 32/48 (67%) returned to independent living. The 32 independent patients, those with "acceptable" outcome, were compared with an "unacceptable" outcome group composed of the 44 in-hospital deaths, the 6 late deaths, and the 16 dependent patients. Factors associated with poor outcome include a GCS score less than or equal to (p = 0.001), age greater than or equal to 75 (p = 0.004), shock upon admission (p = 0.014), presence of head injury (p = 0.03), and sepsis (p = 0.03).(ABSTRACT TRUNCATED AT 250 WORDS)
